Study Notes
Writing Decimals as Fractions
- Decimals can be converted to fractions by using the place value of the last digit. For example, 0.5 = 5/10, which simplifies to 1/2.
- Ensure fractions are reduced to their simplest form for accuracy.
Comparing Decimals
- Practice comparing decimals by looking at their place values.
- Example comparison: 0.2 versus 0.24, where 0.2 < 0.24.
Comparing Fractions
- To compare fractions, find a common denominator or convert them to decimals.
- Example comparison: 3/8 vs. 1/4 can be assessed by converting both to decimals (3/8 = 0.375, 1/4 = 0.25).
Ordering Numbers
- When ordering mixed numbers (e.g., decimals and fractions), convert all numbers to the same form for effective comparison.
- Example: Order 0.2, 4/5, 0.21, 1/4 from least to greatest.
List of Numbers for Ordering
- Order from least to greatest: -10, 2, -0.5, and 5/8 by converting fractions to decimals where needed.
Classifying Rational and Irrational Numbers
- Rational numbers include fractions and whole numbers that can be expressed as a ratio (e.g., 5/6, 0.23, -5 3/8).
- Irrational numbers are non-repeating, non-terminating decimals (e.g., π, square root of non-perfect squares).
Characteristics of Rational Numbers
- Rational numbers can be described as numbers that can be expressed as a ratio of two integers.
- Rational numbers can be positive or negative and include terminating or repeating decimals.
